Nothing in the quotes you posted preclude them using my emails to train AI. They say things like "we process your data according to the agreements we have with you," but that isn't a denial. A denial would be "we don't store or process your data to train AI". They're just implying they don't process your data, while actually saying "the answer to your question lies in the text of the service agreements". Evasive at best. In the absence of a denial, and the presence of an obvious motive to do so, I have to say my guess is they do use your gdocs and gmail data to train AI.
